最佳答案
您的输入图像只有一个分量 channel - 亮度。大多数播放器处理包含三个分量 channel 的 H.264 流 - 亮度或“亮度”(Y)和两个用于色度或“颜色”(U 和 V)。当 H.264 编码器对仅 luma 流进行编码时,它会使用许多播放器无法很好处理的语法来存储它。因此,我们告诉 ffmpeg 在将其发送到编码器之前添加具有中性值的色度分量(因为源中没有色价)。我们将添加最常见的 YUV 编码形式 - yuv420p。
所以,
ffmpeg -y -loop 1 -framerate 30 -t 5 -i SplashBW.jpg -pix_fmt yuv420p Splash.mp4
